It’s a true David vs Goliath story. Well, in this case, it’s a Conor vs The Mountain story.
In a sparring video released to his Youtube page, UFC Featherweight champion Conor McGregor spars with the actor and strongman who plays The Mountain on HBO’s Game of Thrones.
Hafþór Júlíus Björnsson is a 6’9″ 400lb behemoth who is one of the strongest men in the world.
McGregor is only 5’9″ and 145 lbs, but is regarded as one of the best pound for pound fighters in the world.
The pair spars for over 3 minutes without any protective gear.
While McGregor lands some good hits and shows off his technical fighting ability it’s not too hard to see how the massive Björnsson could likely overpower him in a true fight.
